摘要:
The invention describes a composition and method for biochemical and mechanical remediation of wastewater or river in which the biomineral is an oxygen releasing material that increases dissolved oxygen, decreases biochemical oxygen demand and chemical oxygen demand and neutralized strong odor through the use of organo-minerals. The claimed composition comprises of dolostone, organic limestone, rocks, petrified wood, clay minerals and zeolites. The claimed composition is utilized either in powder form and applied through dispersion.

The present invention relates to a method for preparing a superabsorbent polymer. According to the present invention, the method for preparing a superabsorbent polymer carries out, with respect to a polymer obtained by polymerizing ethylenically unsaturated monomers, a re-granulation step by mixing water and a compound of a specific chemical formula. According to the present invention, provided is a method for preparing a superabsorbent polymer, capable of improving the quality of a final resin since the moisture retention capacity thereof is improved and the amount of remaining monomers is reduced.

본 발명은 흡수배율저하 정도가 낮은 고흡수성 수지 및 그 제조 방법에 관한 것이다. 구체적으로, 고흡수성 수지 제조시 단량체 대비 개시제의 양을 최소화하여 분자량이 큰 주사슬을 가지고 높은 겔강도를 유지하는 균일하게 가교된 아크릴 수지를 제조함으로써, 시간 경과후에도 가압시 수분이 베어나오지 않는 리웻 방지 능력이 뛰어나 피부발진을 방지할 수 있는 고흡수성 수지 및 그 제조방법이 제공된다.
摘要:
Diatomaceous earth products with reduced amounts of cristobalite and higher Y values are disclosed. The diatomaceous earth products are prepared in a conventional manner to produce a flux-calcine diatomaceous earth. The flux-calcine diatomaceous earth is mixed with potassium hydroxide and the mixture is then heated. The combination of the potassium hydroxide and post-calcining heat treatment results in a diatomaceous earth product with reduced amounts of cristobalite and a whiter, brighter appearance.
